(3) The transfer characteristic of MOS transistor is the dependence of ( ).
A. Drain voltage on gate-source voltage B. Drain voltage on drain-source voltage
C. Drain current on drain-source voltage D. Drain current on gate-source voltage
(4)The drain of an n-channel MOSFET is shorted to the gate so that VGS = VDS. The
threshold voltage (VT) of the MOSFET is 1 V. If the drain current (ID) is 1 mA for
VGS = 2 V, then for VGS = 3 V, ID is ( ).
A. 2 mA B. 3 mA C. 9 mA
